[Nek5000-users] lelx vs nelx

[nek5000-users at lists.mcs.anl.gov]

Hi,

I am not exactly understanding what is the LELX parameter and how to use it.
( LELX/LELY/LELZ: Maximum number of elements per processor for global 
fdm solver )

and why sometime in the code there is this check
(for example in the  turbchannel's userchk or in genbox.f) :

           if(nelx.gt.lelx .or. nely.gt.lely .or. nelz.gt.lelz) then
            if(nid.eq.0) write(6,*) 'ABORT: nel_xyz > lel_xyz!'
            call exitt
          endif

can anyone help me on that ?


thank you a lot
francesco
